It seems unlikely since Nobels aren't awarded posthumously.
Anything under 3%/year of time until decision is going to have pretty limited predictive value within that range. Anything starting above that range will end up hitting that floor rather than going to zero because of the difficulty of finding a counterparty.
AFAIK there are coins that pay better (some give you exposure to t-bills).
That doesn't mean there aren't other explanations. It could mean that No holders expect to incur an opportunity cost greater than the risk free rate. Combine that with how there's low liquidity (there's less than $300 on the book buying Yes, and at 2 cents or less), and so we could just be seeing the effect of random fish temporarily distorting the price. It could also mean that the risk of a smart contract failing is making it not worth the hassle for a market maker to come in at such a slim margin and low volume.

Why do you need other explanations, when the observed probability can be precisely and fully explained by opportunity cost?
I'd weigh the accuracy by how much money is at stake...
Even then, a "perfect" prediction market need not be accurate, if people use it for hedging. If some low probability event is really bad for me, I may pay over odds (pushing the implied probability up) to get paid if it happens. The equilibrium probability may be efficient, reasonable and biased.
I'm not sure the same(any) rules apply.
It would make the likes of Kissinger getting it easier to understand.
Who's to say a dead person can't have done the most to "promote peace conferences" as mentioned in Nobel's will? These days, I'd say dead people make a larger net contribution to peace than most politicians.
